technical engineer, a subject of the King of Prussia, German Emperor,and a resident of sung teeth.

The body of the cutter is so formed as to constitute at its center aratchet wheel I), which ratchet-wheel is adapted to be turned bysuitable.devices, preferably a Essen-on-the-Ruhr, in the German Empire, pawlc-and a lever 61 on which said pawl is have invented a new and usefulMeans Forming Parallel Faces on the Ends of Rails, &c.,'of which thefollowing is an exact specification.

My invention relates to a means for forming parallel faces on the endsof rails, etc, the main object of the invention being to provide a meansfor accomplishing this result.

The invention is especially applicable to the preparation of the ends ofrails, bars, for welding together, particularly for butt-Welding by thealumino-thermic process. It is of the utmost importance in weldingrails, etc., together, and especially in buttwelding them by the use ofthermit, that the surfaces to be welded be perfectly smooth and parallelin order that they may be in close contact with each other at all pointsin their abutting surfaces. The means which I employ with good resultsfor obtaining the desired parallelism of the abutting faces of rails,etc., is a free rotary cutter having at its sides parallel cutting orfiling faces constructed to have a turning or step-by-step movement forcutting or filing the end surfaces to be faced, and having a peripheryfree from cutting surfaces. When grooved rails are to be brought intocondition for welding the cutter is mounted on a pin passing through itscenter, which pin rests in the groove of the rails at the adjacent endsthereof. The pin, of course, may also rest in any other part of therails, whether they be grooved rails or Vignole-rails. This and otherfeatures of the invention not hereinbefore referred to will behereinafter described and claimed and are illustrated in theaccompanying drawings, in which- Figure l is a side elevation of onetype of means for simultaneously truing or facing the ends of a pair ofrails to bring them into parallelism; Fig. 2 is a plan of the' same, andFig. 3 is a perspective of the same in operative relation with andbetween the ends of a pair of rails.

In carrying my invention into effect I prefer to make use of a freecutter or file body substantially such as shown at a which has at itsopposite sides parallel cutting or for mounted, the cutter faces turningas the 'operatively rails to be faced is clearly illustrated in Fig.-

tor and ratchet-wheel is illustrated as havmg a central journal openinga through which passes a pin f the ends of which project freely and areadapted to rest in the grooves 1' of a pair of rails when the rails tobe welded are of the grooved type. The pin f, projecting on oppositesides, constitutes free centers or arbors projecting from the faces ofthe cutter: Pointed centers'may be used for certain classes of work. Themanner in which the means just described is mounted with respect to the3. The lever 65 may be any suitable for the purpose and may be connectedwith the cutter and ratchet-wheel in any desired manner. I prefer,support it in the manner illustrated, that is to say, by providing inthe periphery of the rotary member a substantially centralcircumferential groove the back wall of which constitutes a journalsurface on which the lever-is mounted to turn. This groove in the rotarymember thus divides the ratchetwheel into two parts, each of which hasits circuit of ratchet-teeth, thepawl 0 being so constructed as tocooperate, with both sets of ratchet-teeth at the same time. Themovement of the filing body may, of course, be also supplied by anyother device, for instance by a steel hoop etc.

. The cutter or file proper may be of any suitable construction, beingmade either entirely'of steel in a single piece or having a body portionof iron with interchangeable cutter disks of steel fastened to the bodyportion, as may be desired. In each case, however, the rotary memberwill have parallel cutting faces at its opposite sides and Willconstitute a duplex cutter or file adapted for simultaneously operatingupon the ends of both of the rails to be faced.

When the rails or other parts are to be faced the cutter and itscarrying means will be placed between the ends of the rails in theposition. shown in Fig. 8, the cutters being turned about thefulcrum-pin f by the lever (Z and the devices operated thereby however,to construct and SCHULTZ, or ESSENI-ON-THE-RIUHIR, GERMANY, 'AssI'oNoRTO-"THE Em t and the rail ends being preferably simul-' taneously forcedup to the cutters, it bein umlerstoodthat one of both of the rails wilbe so held in suitable guides or clamps as to permit at least one of therails to be moved toward the cutters.

\Vhat I claim is:

1. A cutting device for forming uniform pa'rallel end faces on theabutting ends of two articles, said device comprising a rotary memberhaving parallel lateral cutting faces, free centers projecting from saidmember for engagement with work pieces, and means for imparting drivingimpulse to said member.

9. A cutting device comprising a rotary member having oppositely facinglateral cutting faces, Lt'ree arbor centers projecting from said memberfor engagement with work pieces, and means for imparting driving impulseto said member.

A cutting device comprising a duplex cutter having at its opposite sideslateral cutting faces, and also having an intermediate journal portion,free centers projecting from said member for engagement with workpieces, a ratchet wheel in fixed relation to the cutter, and a pawl andlever device for turning said ratchet and cutter, said lever beingmounted on said journal portion of the cutter.

l. A cutting device comprising a rotary member having lateral cuttingfaces, free centers projecting from said member for engagement with workpieces, and means engaging the cutter body circumferentially forimparting driving impulse thereto.

5. A cutting device comprising a duplex cutter having at its oppositesides lateral cutting faces, and also having an intermediate journalportion, a ratchet wheel in fixed relation to the cutter, and a pawl andlever devices for turning said ratchet and cutter,

said lever being mounted on said journal portion of the cutter.

6. A cutting device comprising a duplex cutter having at its oppositesides lateral cutting faces, and also having two circuits of likeperipheral ratchet teeth separated by a peripheral groove forming anintermediate journal, a lever mounted on said journal of the cutterbetween said circuits of ratchet teeth, and a pawl carried by the leverfor engaging said ratchet teeth and turning the cutter.

7. A cutting device comprising a free ro-- tary cutting member havingoppositely facing lateral cutting surfaces and a periphery free fromcutting surfaces, and means embracing said periphery and ada ted toengage the same for imparting riving impulse thereto.

8. A cutting device comprising a free rotary cutting member havingoppositely facing lateral cutting surfaces and a periphery free fromcutting surfaces, and means adapted to engage said cutting member at itsperiphery for imparting driving impulse thereto.

0. Means for forming parallel faces on the abutting ends of rails orother articles to be welded or otherwise joined together, comprising afree rotary cutter having at its opposite sides parallel cuttingsurfaces and a periphery free from cutting surfaces, means forsupporting the cutter in cutting position, and means for engaging thecutter at its periphery for imparting driving impulse thereto.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
